What happens if I purchase stock under NRML?

You can purchase stocks in the NRML order type using collateral margin and hold the position till T+5 days, provided there is no margin shortfall in your position. Post 5 days, liquidation can be done at any point of time from the risk team. Note that if your position is funded by collateral, you will incur interest charges from T+1 day. The interest rate charged is the 'Interest on outstanding debit balance' as specified in your pricing plan. Know more here.
